FAQs
Can I use this on top of existing rust?
It is highly recommended to remove as much loose rust as possible and treat the area with a rust converter before applying the Schutz for maximum longevity.
How long does it take to dry?
The coating is typically touch-dry within a few hours, but it requires at least 24 hours to cure fully before the vehicle is exposed to harsh road conditions.
Is the application gun reusable?
Yes, provided the gun is cleaned thoroughly with the appropriate solvent immediately after each project.
Can I paint over the black finish?
3M Car Body Schutz is designed as a finish coat, but if you choose to paint over it, ensure the product has fully cured and test a small area for paint compatibility.
What is the recommended air pressure for the gun?
Consult the instruction manual included with the 08861 kit, though generally, pressures between 40-60 PSI are used depending on the desired texture.
Troubleshooting
Uneven or blotchy texture
Adjust the air pressure on the application gun or move the spray nozzle at a more consistent distance and speed.
Coating peeling off after drying
This usually indicates the surface was not properly cleaned or was damp during application; ensure the surface is free of grease and moisture.
Gun nozzle clogging
Clean the nozzle immediately after use with a suitable solvent to prevent the coating from hardening inside the spray tip.

Setup, Compatibility & Care
Before starting, ensure the vehicle is clean and the surface is completely dry. Use the provided application gun by attaching it to the 1-litre can and connecting it to a regulated compressed air source. Adjust the air pressure to achieve the desired spray pattern. Always wear protective gear, including a respirator, gloves, and eye protection, to avoid contact with the product. For care, avoid using high-pressure power washers directly on the cured coating for the first 48 hours to allow the material to fully set. Store remaining cans in a cool, dry place away from direct sunlight and heat sources to maintain product shelf life.
